RESUMO
The incidence of postoperative myocardial injury remains high as the underlying pathogenesis is still unknown. The dorsal root ganglion (DRG) neurons express transient receptor potential vanilloid 1 (TRPV1) and its downstream effector, calcitonin gene-related peptide (CGRP) participating in transmitting pain signals and cardiac protection. Opioids remain a mainstay therapeutic option for moderate-to-severe pain relief clinically, as a critical component of multimodal postoperative analgesia via intravenous and epidural delivery. Evidence indicates the interaction of opioids and TRPV1 activities in DRG neurons. Here, we verify the potential impairment of myocardial viability by epidural usage of opioids in postoperative analgesia. We found that large dose of epidural morphine (50 µg) significantly worsened the cardiac performance (+dP/dtmax reduction by 11% and -dP/dtmax elevation by 24%, all P < 0.001), the myocardial infarct size (morphine vs Control, 0.54 ± 0.09 IS/AAR vs. 0.23 ± 0.06 IS/AAR, P < 0.001) and reduced CGRP in the myocardium (morphine vs. Control, 9.34 ± 2.24 pg/mg vs. 21.23 ± 4.32 pg/mg, P < 0.001), while induced definite suppression of nociception in the postoperative animals. It was demonstrated that activation of µ-opioid receptor (µ-OPR) induced desensitization of TRPV1 by attenuating phosphorylation of the channel in the dorsal root ganglion neurons, via inhibiting the accumulation of cAMP. CGRP may attenuated the buildup of ROS and the reduction of mitochondrial membrane potential in cardiomyocytes induced by hypoxia/reoxygenation. The findings of this study indicate that epidurally giving large dose of µ-OPR agonist may aggravate myocardial injury by inhibiting the activity of TRPV1/CGRP pathway.

OBJECTIVE: We aimed to evaluate the effectiveness of ultrasound-guided facia iliaca compartment (FIC) and erector spinae plane (ESP) blocks in managing postoperative pain after total hip arthroplasty surgery. METHODS: A total of 60 patients were randomized into 2 groups (n = 30): one that received FIC blocks and one that received ESP blocks. FIC and ESP blocks were performed with 30 mL 0.25% bupivacaine at the end of the surgery. The patients received intravenous tramadol and patient-controlled postoperative analgesia. The pain scores, opioid consumption, and adverse events were recorded. RESULTS: The dynamic pain scores on movement in the postoperative first hour were significantly lower in the ESP block group than in the FIC block group (3 [2-4] vs 4 [2-5], respectively; P = .035). Data are expressed as median (25th-75th percentiles). Postoperative opioid consumption within the first postoperative 8 hours was significantly higher in the FIC block group than in the ESP block group (80 mg [61-100] vs 100 mg [80-120], respectively; P = .010). The adverse effects of opioids did not differ between the 2 groups. CONCLUSION: ESP and infrainguinal FIC blocks provided similar postoperative analgesia 24 hours after total hip arthroplasty. The ESP block is more beneficial than the FIC block in terms of pain scores and opioid consumption in the early hours of the postoperative period.

AIM: This study aimed to assess the feasibility and effectiveness of the pectoral nerves (PECS) II block in facilitating cardiac implantable electronic device (CIED) insertion in a sample of 120 patients, with a focus on the percentage of cases completed without additional intraoperative local anesthesia. METHODS: PECS II blocks were performed on the left side using ultrasound guidance in all 120 patients. Feasibility was assessed by the proportion of cases completed without the need for extra intraoperative local anesthetic. Secondary outcomes included the amount of additional local anesthetic used, intraoperative opioid requirements, postoperative pain scores, time to first postoperative analgesia, analgesic consumption, patient satisfaction, and block-related complications. RESULTS: Of the 120 patients, 78 (65%) required additional intraoperative local anesthetic, with a median volume of 8.2 mL (range 3-13 mL). Fifteen patients (12.5%) needed intraoperative opioid supplementation. Nine patients (7.5%) required postoperative tramadol for pain relief. In total, 98 patients (81.7%) reported high satisfaction levels with the procedure. CONCLUSIONS: The PECS II block, when combined with supplementary local anesthetic, provided effective postoperative analgesia for at least 24 h in 120 patients undergoing CIED insertion. While it did not completely replace surgical anesthesia in most cases, the PECS II block significantly contributed to a smoother intraoperative experience for patients.

BACKGROUND: This study aimed to observe the effect of opioid-free anaesthesia (OFA) on intraoperative haemodynamic,postoperative analgesia and postoperative nausea and vomiting (PONV) in thoracoscopic surgery in order to provide more evidence for evaluating the safety and effectiveness of OFA technology. METHODS: This was a single-centre retrospective observational study.Adult patients who underwent thoracoscopic surgery with the preoperative thoracic paravertebral block between January 2017 and June 2020 were included.A cohort of 101 thoracoscopic surgery patients who received the OFA technique were matched with 101 thoracoscopic surgery patients who received standard opioid-containing anaesthesia(SOA). Heart rate (HR) and mean arterial blood pressure (MAP) were measured before anaesthesia induction, immediately after endotracheal intubation, at the beginning of surgery, and 10, 20, and 30 min after surgery began.The total amount of intraoperative infusion, frequency of vasoactive drugs use, morphine ingested via the patient-controlled intravenous analgesia (PCIA) 24 h post-surgery,visual analogue scale (VAS) scores at rest and activity on the first day post-surgery, and frequency of nausea and vomiting within 24 h post-surgery were analysed. RESULTS: There was no significant difference in intraoperative HR between the two groups (F = 0.889, P = 0.347); however, there was significant difference in intraoperative MAP (F = 16.709, P < 0.001), which was lower in SOA patients than in OFA patients. The frequency of vasoactive drug use and amount of infusion was less in OFA patients (P = 0.001). The consumption of morphine used by the PCIA 24 h post-surgery was significantly lower in OFA patients (OFA, 1.8 [0, 4.8] mg vs. SOA, 3.6 [0.6, 23] mg, P < 0.001). There was no significant difference in VAS scores at rest (P = 0.745) or during activity (P = 0.792) on the first day post-surgery. There was also no statistically significant difference in nausea and vomiting within 24 h post-surgery (P = 0.651). CONCLUSIONS: This case-control study demonstrated that compared with SOA, OFA can effectively maintain the stability of intraoperative MAP, reduce the incidence of hypotension. Although OFA reduced morphine consumption via the PCIA pump 24 h post-surgery, postoperative pain scores and nausea and vomiting within 24 h post-surgery were similar between the groups.But this study was only a preliminary study and needed to confirm in a larger, more robust trial.

OBJECTIVE: To investigate the analgesic effect of esketamine combined with low-dose sufentanil in elderly patients after gastrointestinal surgery, and whether the anti-inflammatory effect of esketamine is involved in the mechanism of postoperative delirium. METHOD: We enrolled sixty elderly patients (age ≥ 65 years old, American Society of Anesthesiologists (ASA) grade I-III) who underwent gastrointestinal surgery. Patients were randomly assigned to Group C (control group) who received sufentanil 2 ug/kg, and Group E (experimental group) who received sufentanil 1.5 ug/kg + esketamine 1 mg/kg, with 30 patients in each group. All patients underwent total intravenous anesthesia during the surgery and were connected to a patient-controlled intravenous analgesia (PCIA) pump after surgery. The primary outcome was the evaluation of pain at 4, 24, 48 h after surgery which was evaluated by NRS scores. In secondary outcomes, inflammation was assessed by measuring IL-6 levels using ELISA. The postoperative delirium and the occurrence of adverse reactions were observed on the 1st and 3rd day after surgery. RESULTS: The NRS scores at 4, 24, and 48 h after surgery in the experimental group [(4.53 ± 1.22), (3.46 ± 0.73), (1.37 ± 0.99)] were lower than that in the control group [(5.23 ± 1.16), (4.46 ± 0.77), (2.13 ± 0.78)] (P < 0.05). The concentration of serum IL-6 in the experimental group at 24 and 48 h after operation [(15.96 ± 4.65), (11.8 ± 3.24)] were lower than that in the control group [(23.07 ± 4.86), (15.41 ± 4.01)] (P < 0.05); the incidence of postoperative delirium in the experimental group was less than that in the control group (P < 0.05); there was no significant difference in the incidence of postoperative nausea and vomiting between the two groups (P > 0.05), and neither group had nightmares or delirium. CONCLUSION: Esketamine may enhance postoperative pain management compare with sufentanil, and esketamine has anti-inflammatory effects that reduce the incidence of postoperative delirium.

BACKGROUND: Cleft palate repair surgery may result in severe pain in the immediate postoperative period. The aim of this study is to compare the effects of different doses of nalbuphine for postoperative analgesia in children with cleft palate. METHODS: From November 2019 to June 2021, 90 children (45 males and 45 females, age 9-20 months old, ASA class I-II) were selected for palatoplasty. They were randomly divided into three groups: the control group (Group C), the N1 group (postoperative analgesia with 0.05 mg/kg/h nalbuphine) and the N2 group (postoperative analgesia with 0.075 mg/kg/h nalbuphine). Each group had 30 cases. Nalbuphine was not continuously infused in Group C but was continuously infused in Groups N1 and N2 at rates of 0.05 mg/kg/h and 0.075 mg/kg/h, respectively, for 24 h for postoperative analgesia. The FLACC analgesia score and Ramsay Sedation score were recorded at 10 min (T1), 30 min (T2), 2 h (T3), 12 h (T4) and 24 h (T5) after the operation. Adverse reactions such as nausea, vomiting and respiratory depression were observed and recorded. RESULTS: Compared with those in Group C, the FLACC scores in the N1 and N2 groups decreased significantly at T1-T5 (p < 0.05); the Ramsay Sedation score in the N1 group was significantly higher at T3 and T4 (p < 0.05), and that in the N2 group was significantly higher at T1-T5 (p < 0.05). Compared with that in the N1 group, the FLACC score in the N2 group was not significantly different, and the Ramsay Sedation score increased significantly at T5 (p < 0.05). CONCLUSION: Using 0.05 mg/kg/h Nalbuphine continuously for 24 h for postoperative analgesia in children with cleft palate has a better effect and fewer adverse reactions. TRIAL REGISTRATION: This study was registered at ChiCTR1900027385 (11/11/2019).

BACKGROUND: As a novel regional analgesic technique, ultrasound-guided pericapsular nerve group (PENG) block has some potential advantages, and we designed a randomized clinical trial (RCT) to investigate whether the ultrasound-guided PENG block combined with general anesthesia can better reduce stress response, maintain intraoperative hemodynamic stability, and reduce postoperative analgesia in elderly hip arthroplasty compared with ultrasound-guided suprainguinal fascia iliaca block (SIFIB) combined with general anesthesia. METHODS: Seventy-four subjects were enrolled over an 8-month period (20 April 2023 to 31 December 2023). All patients were divided into the test group (group P) and the control group (group S) using the envelope as the randomization method. The test group was treated with preoperative ultrasound-guided PENG block analgesia combined with general anesthesia and the control group was treated with preoperative ultrasound-guided SIFIB analgesia combined with general anesthesia. The primary outcome selected was the patient Visual Analogue Scale (VAS) score at 12 h postoperatively. RESULTS: After generalized estimating equations (GEE) analysis, there was a statistically significant difference in the main effect of postoperative VAS score in group P compared with group S (P = 0.009), the time effect of VAS score in each group was significantly different (P < 0.001), and there was no statistically significant difference in the group-time interaction effect (P = 0.069). There was no statistically significant difference in the main effect of intraoperative mean arterial pressure (MAP) change (P = 0.911), there were statistically significant differences in the time effect of MAP in each group (P < 0.001), and there were statistically significant differences in the interaction effect (P < 0.001). CONCLUSIONS: In summary, we can conclude that in elderly patients undergoing hip fracture surgery, postoperative analgesia is more pronounced, intraoperative hemodynamic parameters are more stable, and intraoperative stress is less induced in patients receiving SIFIB than in patients receiving PENG block.

PURPOSE: Children recovering from anesthesia commonly experience early postoperative negative behaviour, caused by pain and emergence delirium. Differentiating the two is challenging in young children. Perioperative pain influences the heart rate variability-derived Newborn Infant Parasympathetic Evaluation (NIPE) index and may also affect emergence delirium. We sought to investigate whether the perioperative NIPE index can discriminate between mild, moderate, or severe pain levels and can detect emergence delirium. METHODS: This prospective observational study enrolled children aged three years or younger undergoing elective adenotonsillectomy, tonsillectomy, or adenoidectomy. The NIPE index, the Faces, Legs, Activity, Cry, Consolability (FLACC) score, and the Pediatric Anesthesia Emergence Delirium (PAED) score were recorded in the postanesthesia care unit (PACU). The primary aim was to investigate the relationship between the postoperative NIPE index and postoperative pain severity. The secondary aims were to evaluate the association between the NIPE index and emergence delirium (PAED ≥ 10) and its delirium-specific (ED-I) and pain-specific (ED-II) components. RESULTS: Sixty-nine children were recruited. In the PACU, the mean (standard deviation [SD]) NIPE values in children experiencing moderate and severe pain were 50 (12) and 49 (14), respectively. These values were significantly lower than the mean (SD) value of 64 (13) observed in children with mild pain (mean difference moderate vs no/mild pain, -14; 95% confidence interval [CI], -17 to -11; P < 0.001, and mean difference severe vs no/mild pain, -17; 95% CI, -20 to -14; P < 0.001, respectively). The NIPE index was significantly lower in children experiencing pain-specific ED-II (mean [SD] NIPE instantaneous [NIPEi] for ED-II 49 [10] vs no ED-II 55 [13]; mean difference, -6; 95% CI, -11 to -2; P = 0.009). The NIPE index was unable to detect emergence delirium (mean [SD] NIPEi for ED, 54 [15] vs no ED, 51 [10]; mean difference, 3; 95% CI, -2 to 8; P = 0.23) or the delirium-specific component ED-I (mean [SD] NIPEi for ED-I, 55 [15] vs no ED-I, 51 [11]; mean difference, 4; 95% CI, 0 to 8; P = 0.06). CONCLUSION: The NIPE index can identify moderate and severe postoperative pain after adenotonsillectomy but not emergence delirium in children aged three years and younger. This discrimination can be valuable in the early postoperative phase when the differentiation between pain and emergence delirium is difficult.

RéSUMé: OBJECTIF: Les enfants qui se remettent d'une anesthésie font fréquemment preuve d'un comportement négatif en début de période postopératoire. Ce comportement est causé par la douleur et le délire d'émergence, mais il est difficile de les distinguer chez les jeunes enfants. La douleur périopératoire a un impact sur l'indice d'évaluation parasympathique du nouveau-né et du nourrisson (NIPE) dérivé de la variabilité de la fréquence cardiaque et peut également affecter le délire d'émergence. Nous avons cherché à déterminer si l'indice NIPE périopératoire permettait de différencier des niveaux de douleur légers, modérés ou sévères et de détecter le délire d'émergence. MéTHODE: Cette étude observationnelle prospective a recruté des enfants de trois ans ou moins ayant bénéficié d'une adéno-amygdalectomie, d'une amygdalectomie ou d'une adénoïdectomie non urgente. L'indice NIPE, le score FLACC (Faces, Legs, Activity, Cry, Consolability) et le score PAED (Pediatric Anesthesia Emergence Delirium) ont été enregistrés en salle de réveil. L'objectif principal était d'étudier la relation entre l'indice NIPE postopératoire et la sévérité de la douleur postopératoire. Les objectifs secondaires étaient d'évaluer l'association entre l'indice NIPE et le délire d'émergence (PAED ≥ 10) et ses composantes spécifiques au délire (ED-I) et à la douleur (ED-II). RéSULTATS: Nous avons recruté soixante-neuf enfants. En salle de réveil, les valeurs NIPE moyennes (écart type [ET]) chez les enfants souffrant de douleurs modérées et sévères étaient respectivement de 50 (12) et de 49 (14). Ces valeurs étaient significativement inférieures à la valeur moyenne (ET) de 64 (13) observée chez les enfants présentant une douleur légère (différence moyenne modérée vs pas de douleur ou douleur légère, −14; intervalle de confiance [IC] à 95 %, −17 à −11; P < 0,001, et différence moyenne entre douleur sévère vs pas de douleur ou douleur légère, −17; IC 95 %, −20 à −14; P < 0,001, respectivement). L'indice NIPE était significativement plus faible chez les enfants présentant un ED-II spécifique à la douleur (moyenne [ET] NIPE instantanée [NIPEi] pour ED-II, 49 [10] vs pas de ED-II, 55 [13]; différence moyenne, −6; IC 95 %, −11 à −2; P = 0,009). L'indice NIPE n'a pas été en mesure de détecter le délire d'émergence (NIPEi moyen [ET] pour le délire d'émergence, 54 [15] vs pas de délire d'émergence, 51 [10]; différence moyenne, 3; IC 95 %, −2 à 8; P = 0,23) ou la composante spécifique au délire de l'ED-I (NIPEi moyen [ET] pour ED-I, 55 [15] vs pas d'ED-I, 51 [11]; différence moyenne, 4; IC 95 %, 0 à 8; P = 0,06). CONCLUSION: L'indice NIPE permet d'identifier une douleur postopératoire modérée et sévère après une adéno-amygdalectomie mais pas le délire d'émergence chez les enfants de trois ans et moins. Cette discrimination peut être utile dans la phase postopératoire précoce lorsqu'il est difficile de différencier la douleur et le délire d'émergence.

BACKGROUND: The Erector spinae plane block (ESPB) reduces postoperative pain after several types of abdominal laparoscopic surgeries. There is sparse data on the effect of ESPB in laparoscopic ventral hernia repair. The purpose of this study was to test the postoperative analgesic efficacy of an ESPB for this procedure. METHODS: In this prospective, double-blind, randomized controlled study, adult patients undergoing laparoscopic ventral hernia repair were randomly assigned to either bilateral preoperative ESPB with catheters at the level of Th7 (2 × 30 ml of either 2.5 mg/ml ropivacaine or saline), with postoperative catheter top ups every 6 h for 24 h. The primary outcome was rescue opioid consumption during the first hour postoperatively. Secondary outcomes were total opioid consumption at 4 h and 24 h, pain scores, nausea, sedation, as well as Quality of Recovery 15 (QoR-15) and the EuroQol-5 Dimensions (EQ-5D-5L) during the first week. RESULTS: In total, 64 patients were included in the primary outcome measure. There was no significant difference in rescue opioid consumption (oral morphine equivalents (OME)) at one hour postoperatively, with the ESPB group 26.9 ± 17.1 mg versus 32.4 ± 24.3 mg (mean ± SD) in the placebo group (p= 0.27). There were no significant differences concerning the secondary outcomes during the seven-day observation period. Seven patients received a rescue block postoperatively, providing analgesia in five patients. CONCLUSION: We found no difference in measured outcomes between ESPB and placebo in laparoscopic ventral hernia repair. Future studies may evaluate whether a block performed using higher concentration and/or at a different thoracic level provides more analgesic efficacy. TRIAL REGISTRATION: NCT04438369 ; 18/06/2020. .

BACKGROUND: Although video-assisted thoracoscopic surgery (VATS) has advantages of reduced injury and faster healing, patients still endure moderate and severe postoperative pain. Paracetamol and mannitol injection, the first acetaminophen injection in China, has the advantages of convenient administration, rapid onset of action, and no first-pass effect. This aim of this study was to investigate the efficacy of postoperative analgesia with paracetamol and mannitol injection, combined with thoracic paravertebral nerve block (TPVB) in post VATS pain. METHODS: This study was a single-center, prospective, randomized, double-blind controlled clinical trial. Patients scheduled for VATS were randomly divided into three groups, general anesthesia group (Group C), TPVB group (Group T) and TPVB + paracetamol and mannitol injection group (Group TP). In this study, the primary outcome was determined as visual analog scale (VAS) scores at rest and coughing, the secondary observation outcomes were the first time to use analgesic pump, the total consumption of oxycodone in the analgesic pump, number of effective and total analgesic pump compressions at first 48 h postoperatively, the perioperative consumption of sufentanil, time to extubation, hospital length of stay, urine volume, and the incidence of adverse events. RESULTS: In a state of rest and cough, patients in the Group TP showed significantly lower VAS pain scores at 1, 12, 24, and 48 postoperative-hour compared with Group C and Group T. Intraoperative sufentanil and postoperative oxycodone consumption, the first time to press analgesic pump, the times of effective and total compressions of patient- controlled analgesia (PCA) were lower than those of the Group C and Group T. Interestingly, urine output was higher in Group TP. There were no differences between the three groups in terms of extubation time, length of hospital stay and adverse effects, indicating that intravenous paracetamol and mannitol injection is an effective and safe perioperative analgesia method. CONCLUSIONS: Paracetamol and mannitol injection, combined with TPVB may provide important beneficial effects on acute pain control and reduce the consumption of opioid in patients undergoing VATS. TRIAL REGISTRATION: The trial was registered on Jun 19, 2023 in the Chinese Clinical Trial Registry ( https://www.chictr.org.cn/showproj.html?proj=199315 ), registration number ChiCTR2300072623 (19/06/2023).

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR. METHODS: A nested case-control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609). RESULTS: The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence. CONCLUSION: For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases.

BACKGROUND: Erector spinae plane block (ESPB) is a novel fascial plane block technique that can provide effective perioperative analgesia for thoracic, abdominal and lumbar surgeries. However, the effect of cervical ESPB on postoperative analgesia after arthroscopic shoulder surgery is unknown. The aim of this study is to investigate the analgesic effect and safety of ultrasound-guided cervical ESPB in arthroscopic shoulder surgery. METHODS: Seventy patients undergoing arthroscopy shoulder surgery were randomly assigned to one of two groups: ESPB group (n = 35) or control group (n = 35). Patients in the ESPB group received an ultrasound-guided ESPB at the C7 level with 30 mL of 0.25% ropivacaine 30 min before induction of general anesthesia, whereas patients in the control group received no block. The primary outcome measures were the static visual analogue scale (VAS) pain scores at 4, 12, and 24 h after surgery. Secondary outcomes included heart rate (HR) and mean arterial pressure (MAP) before anesthesia (t1), 5 min after anesthesia (t2), 10 min after skin incision (t3), and 10 min after extubation (t4); intraoperative remifentanil consumption; the Bruggrmann comfort scale (BCS) score, quality of recovery-15 (QoR-15) scale score and the number of patients who required rescue analgesia 24 h after surgery; and adverse events. RESULTS: The static VAS scores at 4, 12 and 24 h after surgery were significantly lower in the ESPB group than those in the control group (2.17 ± 0.71 vs. 3.14 ± 1.19, 1.77 ± 0.77 vs. 2.63 ± 0.84, 0.74 ± 0.66 vs. 1.14 ± 0.88, all P < 0.05). There were no significant differences in HR or MAP at any time point during the perioperative period between the two groups (all P > 0.05). The intraoperative consumption of remifentanil was significantly less in the ESPB group compared to the control group (P < 0.05). The scores of BCS and QoR-15 scale were higher in the ESPB group 24 h after surgery than those in the control group (P < 0.05). Compared to the control group, fewer patients in the ESPB group required rescue analgesia 24 h after surgery (P < 0.05). No serious complications occurred in either group. CONCLUSIONS: Ultrasound-guided cervical ESPB can provide effective postoperative analgesia following arthroscopic shoulder surgery, resulting in a better postoperative recovery with fewer complications.

Serratus posterior intercostal plane block (SPSIPB) is a novel periparavertebral block. It provides anterolateral posterior chest wall analgesia. It is an interfascial plane block, performed under ultrasound guidance, and the visualization of landmarks is easy. It is performed deep into the serratus posterior superior muscle at the level of the third rib. Until now, there have been case reports about the usage of single-shot SPSIPB, but there are no reports about the usage of the block catheterization technique of SPSIPB. Continuous infusion from a catheter of interfascial plane blocks is important for postoperative analgesia management after painful surgeries such as thoracic and cardiac surgeries. Thus, we performed SPSIPB catheterization in a patient who underwent right atrial mass excision with minimally invasive thoracotomy surgery. Here, we present our successful analgesic experience with continuous SPSIPB in this case report.

BACKGROUND: The efficacy and reliability of erector spinae plane block (ESPB) in posterior open lumbar spine surgery has been demonstrated; however, few randomized controlled trials of lumbar ESPB (L-ESPB) in lumbar unilateral bi-portal endoscopic (UBE) surgery have been reported. METHODS: A total of 120 patients, aged 18 to 65 (who underwent elective lumbar UBE surgery under general anesthesia and exhibited an American Society of Anesthesiologists physical status of I to III) were randomly assigned in a 1:1 ratio to the ESPB group and the Control group. Ultrasound(US)-guided unilateral single-shot 0.25% ropivacaine L-ESPB was performed in the ESPB group, but not in the control group. Postoperative analgesic strategy for all patients: patient controlled intravenous analgesia (PCIA, diluted and dosed with fentanyl alone) was initiated immediately after surgery combined with oral compound codeine phosphate and ibuprofen sustained release tablets (1 tablet containing ibuprofen 200 mg and codeine 13 mg, 1 tablet/q12h) commenced 6 h postoperatively. We collected and compared patient-centred correlates intraoperatively and 48 h postoperatively. The primary outcomes were intraoperative and postoperative opioid consumption and postoperative quality of recovery-15 (QoR-15) scores. RESULTS: Compared to the control group (n = 56), the ESPB group (n = 58) significantly reduced intraoperative remifentanil consumption (estimated median difference - 280 mcg, 95% confidence interval [CI] - 360 to - 200, p < 0.001, power = 100%); significantly reduced fentanyl consumption at 24 h postoperatively (estimated median difference - 80mcg, 95%[CI] - 128 to - 32, p = 0.001, power = 90%); and significantly enhanced the QoR-15 score at 24 h postoperatively (estimated median difference 11, 95%[CI] 8 to 14, p < 0.001, power = 100%). Compared to the control group, the ESPB group enhanced the resting numeric rating scale (NRS) score up to 8 h postoperatively, and the active movement NRS score up to 4 h postoperatively. The incidence of postoperative nausea and vomiting (PONV) (p = 0.015, power = 70%), abdominal distension (p = 0.024, power = 64%), and muscular calf vein thrombosis (MCVT) (p = 0.033, power = 58%) was lower in the ESPB group than in the control group. Moreover, the occurrence of L-ESPB related adverse reactions was not found herein. CONCLUSION: US-guided L-ESPB reduces intraoperative and 24 h postoperative opioid consumption and improves patients' QoR-15 scores at 24 h postoperatively. L-ESPB can be safely and effectively utilized in lumbar UBE surgery. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR2200061908 , date of registration: 10/07/2022. Registry URL.

PURPOSE: Spinal surgeries are a very painful procedure. New regional techniques for postoperative pain management are being considered. The present study aimed to evaluate the hypothesis that the ultrasound-guided erector spinae plane (ESP) block would lead to lower opioid consumption compared to the thoracolumbar interfascial plane (TLIP) block after lumbar disk surgery. The study's primary objective was to compare postoperative total opioid consumption, and the secondary objective was to assess postoperative pain scores. METHODS: Sixty-eight patients who underwent elective lumbar disk surgery were randomly assigned to either the ESP block group or the TLIP block group. The current pain status of the patients in both the ESP and TLIP block groups was assessed using the Numerical Rating Scale (NRS) at specific time intervals (30 min, 1, 6, 12 and 24 h) during the postoperative period. The number of times patients administered a bolus dose of patient-controlled analgesia, (PCA) within the first 24 h was recorded. RESULTS: In the ESP group, the total opioid consumption in terms of morphine equivalents was found to be significantly lower (ESP group: 7.7 ± 7.0; TLIP group: 13.0 ± 10.1; p < 0.05). The NRS scores were similar between the groups at 30 min, 1, 6, and 12 h, but at 24 h, they were significantly lower in the ESP group. Moreover, the groups had no significant difference regarding observed side effects. CONCLUSION: This study demonstrated the analgesic efficacy of both techniques, revealing that the ESP block provides more effective analgesia in patients undergoing lumbar disk surgery.

PURPOSE: Major spinal surgery causes severe pain. We examined the ability of erector spinae plane block (ESPB) to alleviate pain after posterior spinal fusion (PSF) in paediatric scoliosis patients. METHODS: Seventy-two patients who underwent PSF were randomized into a preoperative ultrasound-guided ESPB group or a no-block control group. The composite primary outcome was the area under the curve (AUC) of the numerical rating scale (NRS) score in the first 24 h after surgery and the number of parent-controlled intravenous analgesia (PCIA) boluses administered 24 h after surgery. The secondary outcomes included the NRS score, opioid consumption, rescue analgesia, adverse events, and quality of recovery. RESULTS: The AUC-NRS at rest was 62 (13) in the ESPB group and 89 (13) in the control group (P < 0.001). There were 15 (5) 24-h PCIA boluses administered in the ESPB group and 30 (7) in the control group (P < 0.001). Compared with those in the control group, the NRS scores at rest were lower in the ESPB group at 0, 3, 6, and 9 h postoperatively, and the NRS scores during movement were lower in the ESPB group at 0, 3, 6, 9 and 12 h postoperatively. The ESPB group showed a lower need for PCIA than did the control group at 0-6, 6-12, 12-18 and 1-24 h postoperatively. In the ESPB group, fewer patients required rescue analgesics, and patients exhibited a higher quality of recovery. CONCLUSION: Preoperative ESPB improves postoperative analgesia in paediatric scoliosis patients who underwent PSF. TRIAL REGISTRATION NUMBER: ChiCTR2300074505. DATE OF REGISTRATION: August 8, 2023.
RESUMO
PURPOSE: Spinal surgery is associated with severe diffuse pain in the postoperative period. Effective pain management plays an essential role in reducing morbidity and mortality. This study is designed to compare the ultrasound-guided erector spinae plane (ESP) block and surgical infiltrative ESP block for postoperative analgesia management after lumbar spinal fusion surgery. METHODS: The patients who underwent two or three levels of posterior lumbar spinal fusion surgery were randomly allocated into one of three groups with 30 patients each (Group SE = Surgical ESP block; Group UE = ultrasound-guided ESP block; Group C = Controls). The primary aim was to compare postoperative opioid consumption, and the secondary aim was to evaluate postoperative dynamic and static pain scores and the incidence of opioid-related adverse effects. RESULTS: There was a significant difference in terms of opioid consumption, rescue analgesia on demand, and both static and dynamic pain scores between groups at all time periods (p < 0.05). Group SE and Group UE had lower pain scores and consumed fewer opioids than the controls (p < 0.05). However, the Group UE had lower pain scores and opioid consumption than the Group SE. The sedation level of patients was significantly higher in the control group than in the other two groups. Also, nausea was more common in controls than in the other groups. CONCLUSION: While both surgical and ultrasound-guided ESP blocks reduced opioid consumption compared to the controls, the patients who received ultrasound-guided ESP blocks experienced better postsurgical pain relief than those in the other groups (surgical ESP and controls).

PURPOSE: Major spinal surgery causes severe postoperative pain. The present randomized, controlled, prospective study tested the short- and long-term effects of thoracolumbar interfascial and erector spinae plane blocks on patient-centered outcomes for major lumbar spinal surgery. METHODS: Sixty adult patients were randomly assigned to receive either bilateral thoracolumbar interfascial plane or erector spinae plane block after anesthesia induction using bupivacaine 0.25%, 20 mL. The primary outcome of this study was the Quality of Recovery-40 score in the postoperative 24th hour. Secondary outcomes were Comprehensive Complication Index scores, postoperative pain scores, opioid consumption, first rescue analgesic administration time, and complication incidence. RESULTS: The recovery scores of both blocks at the postoperative 24th hour were similar, with a median thoracolumbar interfascial plane block of 178 (IQR 173-180) and an erector spinae plane block of 175 (IQR 168.7-182) (p = 0.717). Thoracolumbar interfascial plane block reduced area under the curve pain with movement over 24 h compared with erector spinae plane block (p = 0.024). The pain scores between the groups were similar at all time points (p > 0.05), except the 24th hour with movement in the thoracolumbar interfascial plane block compared with the erector spinae plane block [median 3 (IQR 2-4)] vs. 4 (IQR 3-5), respectively] (p = 0.019). No differences were recorded between the block groups regarding postoperative 24th-h oxycodone consumption, time to first opioid intake, and complication incidence (p > 0.05). CONCLUSIONS: Both blocks resulted in similar quality of recovery in the postoperative 24-h period in major spinal surgery and were effective in terms of analgesia.

INTRODUCTION: Caudal block (CB) and erector spina plane block (ESPB) have been shown to provide effective postoperative analgesia following circumcision. Our aim was to compare the analgesic efficacy of sacral ESPB and CB, as well as the time to first analgesic requirement and postoperative complications. METHODS: Patients aged 1-7 years in the ASA I-II group, who were scheduled for circumcision, were included in the study. Blocks were performed under general anesthesia before the operation. Postoperative pain was evaluated using the Face, Legs, Activity, Cry, and Consolability (FLACC) scores. Analgesic requirements in the first 24 h postsurgery, the time of first analgesia requirement, and postoperative complications were recorded. RESULTS: A total number of 150 patients were included in the study. In the CB group, urinary retention was observed. No side effects were observed in the sacral ESPB group. The 4th and 6th h postoperative FLACC scores were lower in the ESP group. The number of analgesic consumption in the first 24 h postsurgery was significantly lower in the ESPB group (p < 0.001). CONCLUSION: Based on our results, sacral ESPB performed with ultrasonography is a simple and safe regional anesthesia method that can be used to provide effective postoperative analgesia for circumcision.

PURPOSE: This systematic review and meta-analysis aims to assess the efficacy and safety of dexmedetomidine as an adjuvant to intra-articular (IA) injections of local anesthetics (LA) in adult patients undergoing knee arthroscopy. METHODS: We searched MEDLINE, Embase, and Cochrane Library for randomized controlled trials (RCTs) comparing IA dexmedetomidine plus LA versus LA alone for knee arthroscopy in adults. We used the DerSimonian and Laird random-effects model for all outcomes, and conducted a sensitivity analysis with the leave-one-out method, as well as a subgroup analysis for the type of LA. We used R version 4.1.2 for all statistical analyses. RESULTS: We included 16 RCT encompassing 799 patients, of whom 49.8% received IA dexmedetomidine. In the pooled analysis, time to first analgesia rescue was prolonged in almost 4 hours with the use of dexmedetomidine (MD 229 min; p<0.001). We found statistically significant differences favoring dexmedetomidine in pain scores at rest and movement throughout the first 2, 6, 12 and 24 hours postoperatively (p<0.001). Although the mean difference (MD) ranged from -0.3 to -0.9 cm, corresponding to a 3 to 9% reduction in pain scores, this change is not clinically significant when compared to the minimal clinically important difference (MCID). Additionally, the intervention group showed a statistically significant reduction in cumulative opioid consumption over 24 hours (MD -4.5 mg; p<0.001). However, this reduction did not meet the threshold for the MCID. There was no difference between groups on the incidence of hypotension (p=0.190), bradycardia (p=0.430) and postoperative nausea and vomiting (p=0.550). CONCLUSIONS: Adding dexmedetomidine to LA in IA injections for knee arthroscopy significantly extended analgesia duration. Additionally, it lowered pain scores and opioid use, although these effects did not reach the MCID. Furthermore, this addition did not increase the risk of adverse events.
